We have measured the frequency, voltage, and position dependence of the electro-optic response of the charge-density-wave (CDW) conductors TaS 3 and blue bronze at T ∼ 80 K. The response, assumed to be proportional to the local strain of the CDW, i

We have prepared Ag / BSCCO and Fe / Ag / BSCCO planar junctions to study the effect of Fe exchange field on the tunneling spectra. The junctions were constructed so that the tunneling direction is within the ab-plane, either along the maximum or min

We have studied the charge density wave (CDW) repolarization dynamics in blue bronze by applying square-wave voltages of different frequencies to the sample and measuring the changes in infrared transmittance, proportional to CDW strain. The frequenc

We present measurements of the magnetic moment and specific heat of single crystals of insulating ${\mathrm{Pr}}_{3}\mathrm{Ru}{\mathrm{O}}_{7}$, with octahedral $\mathrm{Ru}{\mathrm{O}}_{6}$ and pseudocubic $\mathrm{Pr}{\mathrm{O}}_{8}$ chains, sepa

We have performed temperature-dependent tunneling conductance spectroscopy on ${\mathrm{F}\mathrm{e}/\mathrm{A}\mathrm{g}/\mathrm{B}\mathrm{i}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ (BSCCO) planar junctions. The

Ag/BSCCO and Fe/Ag/BSCCO planar tunnel junctions were constructed in order to study experimentally the effect of an exchange potential on the spin polarized current transported through Andreev bound states appearing at the interface with a supercondu

We have constructed ${\mathrm{MgB}}_{2}/\mathrm{Pb}$ planar junctions for both temperature and field dependence studies. Our results show that the small gap is a true bulk property of ${\mathrm{MgB}}_{2}$ superconductor, not due to surface effects. T

We have measured the magnetic susceptibility (X) and specific heat (cp) of single crystals of Pr 3 RuO 7 . The susceptibility indicates a Neel transition at T N = 54 K, with an unusually mean-field specific heat anomaly. While X indicates that all in
